Shimano 105 ST-R7120 Left Shift/Brake Lever with BR-R7170 Front Brake – Precise Shifting and Reliable Braking

Shimano 105 ST-R7120 with BR-R7170 – a road bike mechanical shifting and hydraulic braking set designed for cyclists who value precise control, reliability and the traditional feel of mechanical shifting. Part of the Shimano 105 R7100 component group, this set combines an ergonomic left-hand shift and brake lever with an efficient front disc brake. It is a practical solution for both upgrading an existing road bike and building a new one where smooth operation, easy maintenance and confident control in a variety of riding conditions are important.

Key features:

• Mechanical 2-speed shifting: the ST-R7120 lever is designed for the Shimano 105 R7100 mechanical 2x12-speed drivetrain, providing precise and reliable control of the front derailleur.
• Dual Control (STI) technology: integrated shifting and braking functions in a single lever allow convenient bike control without changing hand position.
• Ergonomic lever construction: the updated lever shape and brake lever position make the controls easier to reach for different hand sizes and reduce the effort required for braking.
• Reach Adjust: the brake lever reach can be adjusted with a tool to suit individual hand size and preferred grip position.
• Shimano 105 BR-R7170 front hydraulic caliper: provides effective braking and precise modulation in a variety of weather and road conditions.
• Increased brake pad clearance: approximately 10% more clearance between the pads and rotor compared with the previous generation helps reduce the likelihood of unwanted rubbing and brake squeal.
• Ice Technologies cooling system: brake pads with aluminium cooling fins help dissipate heat more efficiently and maintain braking performance on long descents.
• Flat Mount: the compact front brake construction is designed for modern road bikes using the Flat Mount brake mounting standard.
• One Way Bleeding technology: the specially designed hydraulic system makes brake bleeding easier and helps remove air bubbles more efficiently.
• Easy Hose Joint System: the brake hose connection system simplifies installation and hose replacement.
• Pre-assembled hydraulic system: the brake lever and caliper are supplied with a connected, mineral-oil-filled and pre-bled brake hose, helping simplify installation.
• Reliable mechanical operation: the shifting system requires no batteries or electronic components, making it simpler to maintain.
• Compatibility: Shimano 105 R7100 mechanical 2x12-speed drivetrain.
